Abstract (en)

[origin: WO0159340A1] The invention relates to a hand drive (10) for shut-off members, for example for membrane valves. A handwheel (12) for actuating the valve is provided with a closure limiter (32) and a displacement limiter (36). Two inserts (36) are mounted in the handwheel so as to be axially adjustable, said inserts interacting with a threaded spindle (18) coupled with a valve element (16) so as to adjust the displacement limiter and the closure limiter.
